Sep 15, 2018 · The Pecs II nerve block (which also includes the Pecs I nerve block) is an extension that involves a second injection lateral to the Pecs I injection point in the plane between the pectoralis minor and serratus anterior muscles with the intention of providing block of the upper intercostal nerves.

Aug 7, 2019 · The PECS II block targets the anterior and lateral divisions of the thoracic intercostal nerves T2-6, which run in a place between intercostal muscles.

Jul 25, 2023 · The pectoral nerve (Pecs) block I and II are a novel technique to block the pectoral nerves, intercostal nerves 3 to 6, intercostobrachial nerves and the long thoracic nerve. These blocks can be used to provide analgesia for a variety of anterior thoracic wall surgeries, most commonly breast surgery.

Sep 15, 2018 · Features anatomical relationships, sensory block and technique description to perform an ultrasound-guided pectoralis I-II and serratus plane blocks.

In this video we discuss the rationale, anatomy and approach to the pectoralis I and pectoralis II (PECS) blocks and their role in postoperative analgesia for surgery of the breast and chest...

The Pecs II block is a modified Pecs I block and can be achieved with one needle insertion point. Local anaesthetic is placed between pectorals major and minor as for a Pecs I block and then between pectoralis minor and serratus anterior muscles. This results in local anaesthetic spread under the ligament of Gerdy.

Mar 1, 2020 · The pectoral plane nerve block—PECS II is simply a PEC I block with additional injection of local anesthetic between the pectoralis major muscle and the serratus anterior muscle. This allows for local anesthetic to enter to fascial compartments and block not only the medial and lateral pectoral nerves but also the lateral branches of the ...

The Pectoralis blocks can be divided into two separate techniques. The PECS 1 block involves injection of local anesthetic between the pectoralis major and pectoralis minor muscles. The PECS 2 block includes the PECS 1 block with an additional deeper injection between the pectoralis minor and serratus anterior muscles.

This single-centre, prospective, randomised, double-blind trial analysed 45 women to receive either PECs blocks [levobupivacaine 0.25%, 10 ml PECs I and levobupivacaine 0.25%, 20 ml PECs II (PECs group); LA infusion catheter (levobupivacaine 0.1% at 10 ml h −1 for 24 h (LA infusion group); or both (PECs and LA infusion)].

Material and methods: A second version of the Pecs block is described, called "modified Pecs block" or Pecs block type II. This novel approach aims to block at least the pectoral nerves, the intercostobrachial, intercostals III-IV-V-VI and the long thoracic nerve.
